Editor crashes when a floating window PIE command is issued repeatedly

After assigning Keyboard Shortcut for New Editor Window (PIE) as "F3" and returning to Viewport and selecting "F3" to open New Editor Window (PIE), continuing to repeatedly press F3 results in the editor crashing.

Note:

• I was not able to reproduce this in UE4.12.
• I had to repeatedly and aggressively press F3 for this to work in a blank project even though user reports this as occurring frequently and without this extra effort
• I was not able to reproduce this when assigning the Hot key as "X"

1. Open any project in UE4.13
2. In Editor Settings, assign Keyboard Shortcut for New Editor Window (PIE) as "F3"
3. Return to Viewport and hit "F3" to open New Editor Window (PIE)
4. Continue to repeatedly press F3
   RESULT: Editor Crashes
   EXPECETED: Editor to perform without crashing.
